I think 9 volt will be better for tp

Tp is linear regulator so its waste so much power in heat 4.7 to 5v is best when we use above 5v it's heat more and more

I have 5v solar panels. Will these NOT work?

I have it in my blog mate Please check it out there, thanks

Sorry, Can i ask for the connection of solar to esp8266?

​@@nursalwafarahani3277similar as in here, with exception of the powerbooster that you do not need., but you will need an LDO voltage regulator as the battery may go up to 4.2 volts. So: solar panel->TP4065->battery-->3.3V LDO->ESP8266

You are welcome Check out my other videos and subscribe to stay upto date. Thanks again

Check out this little solar idea. kzfaq.info/get/bejne/etZdacmArK-an5c.html

No it doesn't, I am using this setup to power my mailbox notifier for over 2 years and I never had any issues with it.

You may, Just make sure you are producing more than consuming.

HI There According to the datasheet: No blocking diode is required due to the internal PMOSFET architecture and have prevent to negative Charge Current Circuit. You dont need a DW01 coupled up with TP4056 boards. There are two variants of TP4056 boards. One of then already have a n inbuilt protection IC on it. However in general any component you add to a circuit will cause a bit of drop. Cheers

Thanks a lot.

You are welcome

Thanks for watching. More tutorials are on its way. I hope you will like them. 👍

Yes you can remove the battery portion

As per the datasheet: ·Input Supply Voltage(VCC)：-0.3V～8V ·Preset 4.2V Charge Voltage with 1.5% Accuracy I am not sure if you can feed 28v into it. DataSheet:dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf

Most welcome

Hi There If you have a fully charged battery you can definitely connect it to a circuit while charging. The Input Supply Voltage(VCC) is:-0.3V～8V Output voltage: DC 4.2V. 4 chips, with a reasonable turn-off voltage, the charging circuit for each chip set 750mA, total 3A. Input connected two 5A Schottky diodes, 5V standard voltage input chip heat ideal (3.8V battery test). Comes with over-temperature protection, short circuit protection. You can connect two lithium battery cells in parallel to form an equivalent single cell battery with a total capacity of twice that of the individual single cells, but I do not recommend connecting more than two cells at a time to this module. When connecting your lithium batteries in parallel, it is best to charge each battery individually before making the parallel connection(s). With a voltmeter, check the voltage a couple hours after the charge is complete and make sure they are within 50mV (0.05V) of each other before paralleling them.

Thanks a lot for watching, yes you may

You can, but I would not do that, as the boost converter will drain the battery at night, even when the device isn't used. Possibly you could improve it a bit by removing the LED from the boost converter.

Maybe the switch could be replaced by a photocell, a timer, or both.

The TP4056 chip has an inbuilt BMC circuit

First of all thanks for the appreciation and your time. To charge a 9v battery to an optimal level u will need a panel that outputs somewhat similar voltage and high ampere. If you add a booster in the way then you will be wasting a bit of current/voltage generated by these panels.

thanks

I used to have an eBay sellers account, but no more. however u should find all these components easily on eBay or Aliexpress

It will work, Phone batteries generally come with inbuilt protection circuit. Secondly if you have a faulty old laptop, just open up the battery pack and boom you will have 8 18650 batteries :)

keep the protection circuit, it is good to have redundancy. (Li-ion battery fires are not friendly to your house) just solder onto the gold contacts.

Yes, you just need to plug in the USB cable to the TP4056 charger board See the schematics at 03:05

First of all thanks for watching my video. Now the answers are as follows: 1. TP4056 can have an input Supply Voltage(VCC)：-0.3V～8V and Input Supply Current in Charge Mode is between 150 ~ 500μA. A long as u stay under the max limits you will not fry anything. diyfactory007.blogspot.com/2018/04/diy-solar-battery-charger-hi-everyone-i.html 2. If you pump in more current your battery will charge faster. 3.Yes you can

Thank you very much for your answer!

I'm sorry to bother you. I have one more question. The TP4056 specification states that Input Supply Current must be 150 - 500 μA. I have only connected one solar cell (5,5V 0,6W) with wires and the meter shows 83 mA. When I connect 3 in parallel, I'll be 240 mA Why is that? And how do I know that I have not exceeded the required 500 μA?

@@CrazyCoupleDIY Cool answer, ive been researching the TP4056 for a while simply trying to find somewhere where they specify supply voltage parameters. Thanks!

@@CrazyCoupleDIY the answer for question 2 can i ask if i use solar the volt is not limit 8v but the Watt is high stilll can use for this circuit to charge batt fast?

Yes it will, but the rate of charging will be low and the battery will in general never be fully charged.

Thank you for the response. Was planning on using a pair of panels in parallel for 5v 1000mah.

That will do the job I have a similar setup for my letterbox indicator.

The input terminals of the module is recommended to use with clean DC voltages of -0.3V ~ 8V. Generators which are turned by a turbines outputs AC voltages, so you can't connect it directly, without a rectifier and a voltage stabilizer. (I'm no expert here but hope this helps)

@@nubamin8653 thank you it did great video

Yes, it should work Just make sure your charging board has a diode on it to avoid reverse flow of current. If it doesn't just add one to the circuit

Thanks mate

Thanks

You dont need the diode. The datasheet shows that the board has inbuilt reverse voltage protection capability If you add the diode you will loose a bit of current generated

Perfect thanks

Tp4056

@@CrazyCoupleDIY that means the diode is not really needed?

I use 2 x 18650 batteries to power my uno

From Ally Express Look under LED torches.

The switch is to break the battery utilization circuit (the load) from using the battery when its getting charged. You can either use a mosfet/transistor in place of the switch or you can remove it all together. if you add 2 x 1865 in series you will get more voltage output so you may not need a booster, but in that case you will need a powerful solar panel If you add the 2 x 1865 in parallel then you will only increase the current and not the voltage output. In this case again you will need a panel with higher wattage output

@@CrazyCoupleDIY awesome thx soo much!

If I did one then it should be here mate diy-projects4u.blogspot.com/

Thanks

Actually, u are right

Referring back to your comment: You definitely need a Diode reason: TP4056 has no inbuilt MOSFET, and hence a Sense Resistor or Blocking Diode is Required

It should be ok as long as you have the diode in place. The diode will stop the backward flow of electrons

Now that you mentioned it has Reverse voltage protection in some other comment, do I still need a diode for this scenario (both usb + panel)

It will work without the diode The diode is just for an extra level of protection. However there is a bit of current/voltage drop if you put the diode.

The circuit would be the same but it will take longer to charge the batteries. In general, terms, if you increase the number of batteries you need to increase the amount of current flowing out from the panel to the batteries (so may be try a bit more wattage)

@@CrazyCoupleDIY OK, so more solar wattage needed, check! thank you!

@@CarneSagrado Yes you need a more powerful pannel :)

Crazy Couple would a 9v solar panel work with this system?

@@markbriggs5110 9v will burn the TP4056 chip as the Input Supply Voltage(VCC)：-0.3V～8V Please have a look at the datasheet : dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf

That’s is correct

can give example what solar panel can use

@@mohdazri1170 I fucking hate you more now

You can place an order via my website or from eBay Th total cost was under $10

The Output Voltage of tp4056 is 4.2 V Hence you cannot attach a 9V batter.

You need a panel which can pump more current than normal.

Depends on the level of tolerance

2 batteries will need more wattage. Which mean you either can add more panels or single panel with more wattage In simple terms more electrons are needed.

Hi there Yes you can definitely bypass the TP4056 board The reason I have added it to the circuit is to protect the battery from over or under charging. These batteries can catch fire if they become too hot or will completely die if they loose all their charge.

With the TP4056 board with two outputs, how does that wiring work? the B+ and B- to the battery and the other outputs directly to the 5V voltage booster?

Yes, please have a look at the video. I have explained it in there. Basically thats the way the battery is protected from under or over charging.as soon as the max or min point is reached the circuit cuts off the connection between the battery and the output pins.

upon assembly of this circuit, I have a red light in the TP4056 board but the phone still doesn’t charge. If i plug the TP4056 into a power source the phone begins to charge… therefore i believe my circuit is wired correctly… does the board just need to change up? before it will work and charge a phone? let me know some steps in troubleshooting this!

CheMur PS solar panel current must be really low. What solar panel are using?

You will need panels which can output more current in that case

I don't see why not

You need panels with more watt output. I have a setup that charges 2 x 18650 batteries using 4 x 6v, 1.5 amp panels

This setup is to charge a 18650 battery which has the following specs Nominal Voltage: 3.6V. Nominal Capacity: 2,850 mAh. Minimum Discharge Voltage: 3V. Maximum Discharge current: 1C. Charging Voltage: 4.2V (maximum) Charging current: 0.5C. Charging Time: 3 hours (approx) Charging Method: CC and CV. If the Li-ios you are charging falls between these specs then you should be able to, otherwise you may need more panels and few more of the protection circuits. In reality one protection circuit should be used for 1 cell (they are dead cheap anyways)

@@CrazyCoupleDIY thank you!

Sure you can I don’t see any reason why not

@@CrazyCoupleDIY thank you so much have a good day!!!

Sure you may

134N3P is a similar battery charging board with protection, so the answer is yes

You will need to add a booster

TP4056 has: Input Supply Voltage(VCC)：-0.3V～8V The charge voltage is fixed at 4.2V So to charge a "single 12 V battery" you will need more power. In general terms, you just need to add the chips in series to sum up the output voltage to the threshold and then use some voltage regulators to have it fixed @ 12V But to charge a 12 v battery you will have to use solar panels with more wattage I hope this helps

@@CrazyCoupleDIY tanks but where can i get TP4056 and 1n4007 diode, SPDT switch , solar?

eBay or AliExpress

sure u may, but just be careful of the pin out

@@CrazyCoupleDIY thank you

@@CrazyCoupleDIY sorry can i ask you what pin out?

You can add more batteries in parallel that way voltage remains same but current buffs up. But you will also need more panels to charge them

@@CrazyCoupleDIY that would work for me but how I can calculate how much batteries I need for all the night xD

Try this online calculator www.powerstream.com/battery-run-time-calculator.htm

If your question is: what is the maximum capacity of the battery (18650) that I can connect to the tp4056? The answer is: ·Input Supply Voltage(VCC)：-0.3V～8V ·TEMP：-0.3V～10V ·CE：-0.3V～10V ·BAT Short-Circuit Duration：Continuous ·BAT Pin Current：1200mA ·PROG Pin Current：1200uA ·Maximum Junction Temperature：145℃ ·Operating Ambient Temperature Range：-40℃～85℃ ·Lead Temp.(Soldering, 10sec)：260℃ ·Preset 4.2V Charge Voltage with 1.5% Accuracy ·2.9V Trickle Charge Threshold (TP4056)

Yes it can, but not without the battery. Solar panels wont have enough current to power an arduino. So you need to charge the battery using this circuit and the battery will power the Arduino

@@CrazyCoupleDIY how can I do that please need your help for my project

@@theolix9938 ya same like you

IN+ and IN- are for the input, B+ and B- is where the battery connects to and OUT+ and OUT- is where your devices are connected. So basically if the voltage is low or high the OUT will not output anything Let me know if you need further clarification This is my Blog: diyfactory007.blogspot.com.au just for your reference

Crazy Couple thank you xD and one more question xD how to connect voltage booster with it all? btw great video, keep it up xD

Just connect the IN+ and IN- of the booster to the OUT+ and OUT- of the TP4056 board. The booster outputs the voltage from the USB port, so you need to connect a USB cable to harness the boosted Voltage. Thanks again for watching, stay tuned for more amazing videos :)

TP4056 can have an input Supply Voltage(VCC)：-0.3V～8V and Input Supply Current in Charge Mode is between 150 ~ 500μA. A long as u stay under the max limits you will not fry anything.

@@kanika1084 Yeah that's why I was asking cause more current shouldn't harm anything right? Also due to 500 ma of current the charging is tremendously slow

That is right guys

@@CrazyCoupleDIY so bro should I supply my tp4056 board with5v 2 amps

As per Kanika’s comment and the data sheet the board will fry up if you feed 2amps of current into it

Sure is, but you will need 2 to 3 of those solar cells as one is not sufficient to provide enough current to charge a phone.

Crazy Couple alright..thank you so much

Pleasure, I will publish a DIY charger box video soon It will be multifunctional charger box. Stay tuned for that :)

Crazy Couple noted.I will wait for that video

That is absolutely right.

@@CrazyCoupleDIY I'm messing with a TP4056 right now for the same kind of application and watching KZfaq videos is always part of any research! Another improvement would be to desolder the red led to save a few more mA when charging. I'm using a 5W thin film panel with indirect light, for charging a 300mAh li-ion battery in my small world band radio (normally run on two AA cells), I use it as a clock radio to wake me up each morning, and it works perfectly playing news for one hour each day on the sparse sunlight it gets a few meters from the bedroom window. I'm in the process of eliminating parasitic power use in my home, and my previous LED clock radio with and old style transformer used 6W according to my new digital meter. This one runs for free.

Just pinched the red led off with pliers. Now the solar panel is at 3.76V while the battery is at 3.52V, that is only 23mV drop, quite good, so the TP4056 is very suited for solar applications.

Good work nice finding. I will pin your comment to the post

Thanks my friend

You better of using this just to change a battery with in turn can drive the motor

1. You definitely can. I have a weather station running 24 x7 2. The board has under and over charging protection So no worries mate

This setup should work flawlessly Just attach your Arduino's Vin and negative to the output of the booster

@@CrazyCoupleDIY can I charge a li-ion battery pack that contains 4 li-ion battery using this setup as well or do you have any recommendations. Thank you so much for your time!

Aliexpress

@@CrazyCoupleDIY I don't understand

@@CrazyCoupleDIY how do I get it

The circuit will still work even if you dont add the switch in between I added it to avoid charging and discharging at the same time.

Thank you for the prompt reply. I am asking to know if there is any side effects for charging and discharging in the same time? will that cause any serious issues?

Not really, I have a remote logger installed on my roof and it works fine with this setup. I also use this for my smart letterbox and i never had any issues. Both setup dont have the switch in it. Unless your circuit is draining the battery drastically this setup will work without any issues. The only thing is you will never get the green light (fully charged indicator)

Nice :) I am making an autowatering system that will just wake up every hour so I dont think it will cause any issues btw I am so much interested in seeing your other two projects any plans on making videos about them ? I am also planing to make a letter box notifier :D

IT should work without any issues mate. Yes, Currently I am making a video on automatic garage lighting system, and the next one will be on garage door opener with few other features that you will not find on any other blog. Sure I will create tutorials on them in near future Stay tuned and best of luck for your project :)

Yes u may

Yes foe sure

If your solar panel can provide enough “current” then it’s fine. Moreover Adding a battery will keep ur circuit active when the sun is set.

Crazy Couple but i already try .. it not charge the fone or power bank . Can help me bro?? This for my final project

How much current is produced by ur panel? To charge a phone/powerbank you need more current on whatever voltage its outputting. You atleast need 1.5 Watt output

Crazy Couple i will buy your project .. can me buy it ?

I will suggest you the components and you can buy them off internet

Yes it does But you may need to add a panel with higher wattage

Any sugesstion?

I power my NodeMCU using a 1.5W panel and it works like a charm It cost me $3 from eBay

Ok, so i need a 1.5W panel to power my arduino, thanks for the help my friend

Pleasure

The connection is done as per the diagram mate.

BT modules consume lot of power. In general any wifi module drains out battery pretty quickly unless you put it on sleep or use interrupts. LEDs are also massive power drainers. The best way would be to connect a multimeter in series and calculate the power consumption and then do your math and see how long the device will last on a fully charged battery and based on your math you can find out how much power you need to charge them back up.

First of all thanks for stopping by. 1. That should be fine 2. I dont see anything that will stop you from doing that 3. Yes. I have a small RC car that I created, which has 3 of the 18650 batteries. Each battery has their ow BMC (battery management circuit) to avoid over or undercharging

@@CrazyCoupleDIY you were really helpful, thanks. Wish to see more from you. keep up, bro.
